Reagan County · Big Lake (Ellenburger) field · Horizontal · Sidetrack
University #212 (API 42-383-33976) is a plugged horizontal well in Reagan County, plugged February 26, 2025, last operated by Apache Corporation.
The RRC has issued 2 drilling permits (amended once) between 1989 and 1998, permitted to 8,900 ft.
It was permitted by Marathon Oil Company and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 4 formation tops, including Grayburg, Spraberry, Dean, Ellenburger.
Its lease has reported 505K barrels of oil and 3.05M mcf of gas since January 1993, last reporting volume in April 2024. The lease carries 9 wells, so these are lease totals, not this well alone.
